Salivary profile of children with erosive tooth wear: a transversal study.

The aim of the present transversal study was to evaluate the clinical and biochemical salivary parameters of children with and without erosive tooth wear (ETW). The study population was children aged 4 to 9 years. A trained and calibrated examiner (kappa value for intraexaminer reliability = 0.

Assessment of oxidative stress in saliva of children with dental erosion.

Objective: To evaluate oxidative stress in saliva of children with dental erosion as compared to children with no erosion.

Methods: One single examiner, trained and prepared to make diagnosis of dental erosion according to the Basic Erosive Wear Examination index, selected 40 children aged 4 to 6 years, who attended a pediatric dentistry prevention clinic. Two groups were formed - one comprising children with dental erosion (n=22), and another with no dental erosion (n=18).

Dental students' and lecturers' perception of the degree of difficulty of caries detection associated learning topics in Brazil.

Purpose: It aimed to explore the degree of difficulty of caries-detection-associated-topics perceived by dental students and lecturers as pedagogical step in the development of learning objects for e-learning.

Methods: A convenience sample comprising ninety-eight subjects from different academic levels (undergraduate/graduate students and pediatric dentistry lecturers) participated. Two spreadsheets (isolated/relative) were created considering key topics in the caries detection process.

Exploring some aspects associated with dentine hypersensitivity in children.

Background: The etiology of dentine hypersensitivity (DH) is still inconclusive and there are few studies concerning it in children.

Aim: To evaluate clinical, dietary, and salivary variables in children with DH complaints.

Design: Forty-eight children were asked about DH.

Associated factors to erosive tooth wear and its impact on quality of life in children with cerebral palsy.

To evaluate the presence and associated factors of erosive tooth wear (ETW) in children with cerebral palsy (CP), as well as its impact on the oral health-related quality of life (OHRQoL). Parents of 60 CP children, between 6 and 14 years of age, answered the Brazilian version of the parental-caregivers perception questionnaire (P-CPQ). The ETW diagnosis was performed by a single calibrated examiner according to the O'Brien´s modified index.

Effect of topical application of fluoride gel NaF 2% on enzymatic and non-enzymatic antioxidant parameters of saliva.

Objective: The aim of the study was to evaluate the effect of topical fluoride gel NaF 2% application on antioxidant parameters of whole saliva from children.

Design: The saliva mechanically stimulated with parafilm was collected from 25 children (6-12 years) attending the Clinic of Paediatric Dentistry of Universidade Cruzeiro do Sul, São Paulo, Brazil, before (control group) and immediately after application of neutral fluoride gel NaF 2% (fluoride-gel group), according to the Standards for Research Using Human Subjects, Resolution 196/96 of the USA National Health Council of 10/10/1996. Afterwards, pre-post ferric-reducing antioxidant power (FRAP), trolox-equivalent antioxidant capacity (TEAC), uric acid, reduced/oxidised glutathione content (GSH/GSSG) and total peroxidase activity (TPO) were evaluated in whole saliva of both groups.
